Thomas Neidhart commented on COLLECTIONS-503:
---------------------------------------------
Yes you are right. We can not easily remove classes, thus it is better to add
an IfTransformer class to be consistent.
Just add a unit test please.
There are not yet many in the functor package, but we need to start somewhere.

> Just thought a basic ifTransformer that performs operations based on a
> predicate would be useful. I know this functionality can be accomplished via
> a switchTransformer, but sometimes it would just be easier and more clear to
> have an ifTransformer.
> I attached a draft of what it could look like. Let me know if this is
> something that should be included and I can polish it and write some tests.
